Array substrate, display panel and display device

An array substrate, comprising:

• a plurality of sub-pixel units arranged in an array on a base substrate, wherein:
• each of the sub-pixel units comprises a pixel circuit structure and a light-emitting element;
• the pixel circuit structure comprises a driving transistor, a first reset transistor and a second reset transistor;
• each of the driving transistor, the first reset transistor and the second reset transistor comprises an active structure, a first insulating structure on the active structure, and a first metal layer structure on the first insulating structure;
• the active structure of the first reset transistor of an i-th row of sub-pixel unit is electrically coupled to an anode of the light-emitting element of the i-th row of sub-pixel unit, and is electrically coupled to the active structure of the second reset transistor of an (i+1)-th row of sub-pixel unit, i being an integer greater than 0;
• and
• in each of the sub-pixel units, the first metal layer structure of the driving transistor is electrically coupled to the active structure of the second reset transistor.
